Max voltage safe for all electronic devices?

Millivolts can heat up milliohms.

Ionizing a component? Do you mean vaporizing it?

I think you are wrong. I was told it was 47.5

Hi:

What is the maximum voltage possible *without* doing any of the following to any extent?:

1. Exceeding the dielectric strength of any electronic component

1. Generating temperatures above 70 Fahrenheit in any electronic component

2. Ionizing any electronic component

Thanks,

i think 42 just might be the ultimate answer... but don't make a typo because it definately is not 32 , that is a bad #, because that destroys lots of stuff

THis is quite easy. its 0.

But 42 is THE answer to all questions about the Universe.

At least it is the answer to all Radium ranti...pardon.. questions.

While 42 is fine and well for most situations, I've always had a mysterious draw to 666. It has never let me down.

You said "dielectric strength."

Sure.

Beyond 70 Fahrenheit?

Naw. Plug your circuit into that and all you'll get are fire and brimstone.

That's only for small values of 47.5

Isn't the damage to the CPU caused by a mixture of excessively high temperatures and dielectric breakdown?

Also, dielectric breakdown [even without significant heat] damages flash RAM chips [which is why they don't last too long]. The electrons pierce the insulations within the chip.

How can a millivolt generate temperatures above 70 F in a milliohm? Both the voltage and the resistance are too small to generate such high temperatures. Right?

One millivolt across one milliohm is still one amp. What about several millivolts?

Current is still V/R, so 23 (another magic number) millivolts across a one inch length of #20 wire (about 1 mOhm) will produce 23 amps. And power is V*I, so you have about half a watt. Doesn't sound like much, but it's enough to melt the wire, especially if it is enclosed in thermal insulation. If you operate a 1/2 watt lamp in a well insulated box, the air inside will get well above 70F. Temperature depends on heat conduction and radiation. So, imagine how hot a tiny IC bonding wire could get with just

He didn't say "a millivolt", he said "millivolts". E.g. 100mV into 1mOhm =

A much smaller power dissipation can still produce high temperatures if the thermal resistance is high enough.

About 0.56V.

What do you do if the ambient is >70F?

Thanks.

Thats okay. I just don't want anything inside to get damaged
